Used primarily as a biocide in industrial water treatment systems to control microbial growth, particularly in cooling towers and paper mill systems. It is effective against a broad spectrum of microorganisms, including bacteria, fungi, and algae. Its lipophilic nature allows it to penetrate biofilms, enhancing its antimicrobial efficacy in hard-to-reach areas. Also employed as a preservative in aqueous-based products to prevent spoilage due to microbial contamination. Shows utility in antifouling coatings for marine applications by inhibiting the attachment and growth of organisms on submerged surfaces.
